-
-mig-quicksheet
-
-Quickly produces a simple Excel spreadsheet based on the tracked file suitable
-for simple end-user mapping. The new file is named after the tracked file, but
-ends in .mapping.xls
-
-Multiple files may be specified, in which case all of the results are
-concatenated into one spreadsheet named <migration_schema>.mapping.xls
